Best ResponseYou've already chosen the best response.1so it is either the 14th term or the second term depending on how you are counting. makes no difference. the term looks like \[\dbinom{16}{2}(x^3)^{14}(3)^2\]

Best ResponseYou've already chosen the best response.1\[\dbinom{16}{2}=\frac{16\times 15}{2}=8\times 15=120\] and \((3)^2=9\) multiply to get your answer
